Adenoid cystic carcinoma of the prostate – A rare case of genitourinary malignancy

A 72 year old was referred to the Urology department with lower urinary tract symptoms (LUTS), an abnormal prostate on digital examination and a serum prostate specific antigen (PSA) level within normal limits. A flexible cystoscopy revealed no abnormality of the urethra and an obstructive prostate. Magnetic resonance imaging (MRI) revealed a 4.3× 4cm soft tissue mass on the posterior corpus spongiosum encasing the bulbar urethra with tumour abutting the prostate. Transperineal prostate biopsies confirmed adenoid cystic carcinoma. Cross-sectional imaging arranged for staging, revealed multiple pulmonary metastastis. The patient is currently being treated with tyrosine kinase inhibitor medication.
